There’s growing evidence that people and the planet are increasingly impacted by extreme events. According to the Fourth National Climate Assessment, published in 2018 by the U.S. Global Change Research Program, “more frequent and intense extreme weather and climate-related events, as well as changes in average climate conditions, are expected to continue to damage infrastructure, ecosystems, and social systems that provide essential benefits to communities.”      As the impacts of extreme events continue to mount, interest has grown in the scientific community to study whether specific extreme events can be partially attributed to human activities. With the help of climate models, scientists have conducted an impressive array of studies, looking for possible links between human acti... Ver mais

Judge the following item according to the text above.

Experts predict an abrupt change in climate conditions due to continually harmful human activities.  

According to the text above, judge the following item.

From 2013 to 2019, the percentage of sites in European surface waters whose levels of pesticides are above the limits more than doubled.

According to the text above, judge the following item.

Contamination by pesticides in European waters is less likely to occur than in other places in the world due to strict control policies. 

   In May 2021, a hole was found in a robotic arm aboard the International Space Station (ISS). The suspected culprit was a piece of rogue space junk. While thankfully no astronauts were injured, it has re-focussed attention on the growing problem of orbital debris.
How did we get here?   It’s easy to forget that just seven decades ago the Moon was the only thing orbiting the Earth. On 1 January 2021 there were 6,542 satellites in orbit. Tellingly, only just over half of them were active. That’s a lot of useless metal careering around the planet at 28,000 kph — ten times faster than a bullet.
How bad is the problem?     Very bad and getting worse. Estimates suggest there are currently half a million pieces of debris the size of a marble or larger and... Ver mais

In the third sentence of the fourth paragraph, the pronoun “it” refers to Intel. 

   Jack Kilby’s revolutionary idea was to make all the different components of a circuit out of the same flat block of semiconductor material. Not only would this get rid of wires and faulty connections, it would make the entire circuit much more compact. Kilby demonstrated his first “integrated circuit” on Sept. 12, 1958.   Six months later, in California, another engineer, Robert Noyce, independently came up with the idea of making an integrated circuit. Noyce’s chip was better suited to be manufactured in large numbers, and soon he was part of a young company called Intel.   Thus was launched a revolution. The first chip-based computer was the first U.S. Air Force computer, built in 1961. The true potential of the integrated circuit was shown when Texas Instru... Ver mais
